Determination of Lethal Concentration of Some Insecticides to Honey Bee Apis Mellifera (Apidae, Hymenoptera) with Laboratory Bioassays

Abstract

The study, efficacy of three insecticides including Carbaryl, Carbosulfan and Methiocarb were evaluated in laboratory bioassays and lethal concentrations were determined against honeybee adults. The highest toxicity based on LC<inf>50</inf> values was observed in carbosulfan (1.3 mg AI L-1). The LC<inf>50</inf>'s (mg AI L-1) for methiocarb and carbaryl in topical application method were 65.9 and 71.7, respectively. © Medwell Journals, 2009.
